How do you change the default messaging picture when sending text on the S5?

[Nezello]

I got a new Galaxy S5 and when I send someone a text it shows my Gmail picture next to my name, I do not want this. So I clicked on my picture while viewing a message and behold it takes me to my info, there it shows an edit icon on my local picture. I clicked to change it which it shows successful however it keeps showing the default Gmail picture when I send a message. How do I make it stop?? I even tried display no picture. Any help would greatly be appreciated!!

Is that same pic tied to your G+ profile?
